I am buying a 302 motor off a guy who recently bought a camaro. He built the engine and told me that I would need a carburetor for it. I know they come fuel injected but would a carb give it more horses? Or just less gas mileage? Which would be more expensive and harder to install? And last, which would you do?


Also which are better pistons? Dome shaped or regular flat topped? The motor has been completely rebuilt, but he still needs to put pistons in it.

if you have to pass emissions than fuel injection.

If you don't already have all the efi stuff, just carb it.

Dome will give you higher compression, just be careful no matter which pistonsits not more than 11.1 then you will probably have to run racing gas all the time, also you will never be able to supercharge or turbocharge it.

Don't think I have to pass emissions. I wouldn't think so because I haven't done so yet. So the carb would be the better option to go? Easier to install? Cheaper?

probably

I was a carb guy for a great many years, especially in the lean years for Motorsports when the 5.0 was just gaining popularity and there were practically no adequate F/I components to build big horsepower. Now you will get the "F/I is too expensive blah blah blah" but basically from all my years of jacking with these things, Fuel injection is flexible, readily expandable and capable of way more potential then most ever use. If you have all of the wirinf harnesses and the brain, I would go that way, if not you would have to buy another brain and harnesses which is really no big deal. You will spend time on them either way. Fuel injection from my actual experience is easier for daily driving. I am building what was originally going to be another pro-fogger carb car and is now going to be a big blower car with F.A.S.T. cause it's only money.

I got a question.
How could the guy you want to buy the motor from have it 'completely rebuilt but still needs pistons'?
Something not right here, IMHO.
I would stay with a flat top type as I think that when the plug fires, it would be a good idea to have ALL the mix in the chamber fire as fast as possible.
That makes HP without high heat.........
High compression makes higher heat.........

i agree completely rebuilt but i needs pistons? are the heads still on it. does he have any proof of the work?

also this topic has been covered try the search button next time.

Fuel injection is best if you can afford it, plain and simple. It makes more power, provides better drivability, and has endless tunability. If you can't afford it, a carb won't let u down.
